Why a 100 KB limit?
A 100 KB limit is the strictest you'll commonly meet, and it almost always comes from an official portal: exam and recruitment applications (SSC, UPSC, IBPS and similar), visa and passport forms, scholarship portals, and e-government services that were built for slow connections. A single page scanned by a phone camera is often 1–2 MB — ten to twenty times over the limit — so nearly every scanned document needs compression before these portals accept it.
This tool works backwards from the limit: it re-renders your pages and steps down resolution and quality until the file fits under 100 KB, then hands you the best-quality version that made it. No slider guesswork, no trial and error.
Getting under 100 KB: what realistically fits
100 KB is small. As a rule of thumb, it comfortably holds 1–3 pages of scanned content at readable quality, or many more pages of pure digital text. If your document is longer and won't fit, three tricks help:
- Split first, compress second. If the portal accepts separate files, use our Split PDF tool to extract only the required pages, then compress those.
- Check what's actually required. Portals with 100 KB limits usually want a single document (one certificate, one photo page) — not your complete file bundle.
- Accept the readability trade-off consciously. The tool will warn you instead of silently delivering an unreadable file if 100 KB is physically impossible for your page count.
How to compress your PDF to 100 KB

- Compress. The target "Under 100 KB" is already selected. Click Compress PDF.
- Download. Check the before/after size and save the copy. Your original stays untouched.
Frequently Asked Questions
Why do government portals demand 100 KB files?
Many application systems were designed for slow connections and limited server storage, and the limits were never raised. The requirement is strict — files at 101 KB get rejected — which is why this tool compresses to safely under the limit.
How many pages fit into 100 KB?
Roughly 1–3 scanned pages at readable quality, or more for pure text documents. For longer files, split out the required pages first, then compress.
My document is sensitive (ID, certificate). Is it uploaded?
No. Compression runs entirely in your browser — the file never reaches a server. That is exactly why EveryPDF is safe for application documents.
What if my PDF can't reach 100 KB?
The tool tells you openly and offers the smallest achievable file. In that case, reduce the page count with the Split tool and try again.
